You have planted a harlequin willow and are unsure how much and what fertilizer the tree needs? Then you have come to the right place on this page. Here you can find out everything about suitable products, the right time and the frequency of fertilizer application.
How often should you fertilize a harlequin willow?
Harlequin willows rarely need fertilization: feed free-standing plants once a year with organic fertilizer such as compost (€43.00 on Amazon) or mulch, ideally during budding. Potted plants benefit from monthly fertilizer applications of the same type of fertilizer.
The right substrate
Harlequin willows place only minor demands on the soil. Both keeping in containers and planting in the topsoil are possible. In both cases, the harlequin willow is content with conventional garden soil. The prerequisite is that your garden has the ability to store water and provides sufficient nutrients. Otherwise, you should help with some organic fertilizer.
Fertilizer application
- If you have planted your harlequin willow in the ground, fertilizer is not absolutely necessary
- As a precaution, you can give complete fertilizer once a year
- The flat roots of the harlequin willow get the nutrients they need on their own
- It is best to fertilize during sprouting
- Prefer organic fertilizer such as compost (€43.00 on Amazon) or mulch
- Mulch and compost simultaneously protect the substrate from drying out and thus reduce the amount of watering
- If growth is weak, you can give the harlequin willow another dose of fertilizer until August
- Do not fertilize your harlequin willow before winter
- This could cause the tree to sprout again
Tip
In winter the harlequin willow sheds its leaves. Make a compost out of it. Next year you can use the leaves as fertilizer.
Harlequin willow in a bucket
Unlike free-standing plants, the harlequin willow in a pot definitely needs monthly fertilizer. Although the wide roots usually get enough nutrients, they have far less space in the pot. The limited space does not provide enough minerals. Here too, complete fertilizer is completely sufficient. You generally can't go wrong with compost and mulch.
